Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed J une 20,1904. Serial No. 213,402.

T0 all whom it may concern,.-

Be it known that I, ARCHIBALD W. F. STEGKEL, a citizen of the UnitedStates, residing at Columbus, in the county of Franklin and State ofOhio, have inventedl certain new and useful Improvements inConveyer-Belt Supports, of which the following is a specication,reference being had therein to the accompanying drawings.

My invention relates to that class of conveyers in which idler pulleysor rollers are employed for giving to a conveying-belt atroughlike formfor the purpose of better retaining the material conveyed within theedges of the belt.`

The invention consists in the parts and combinations thereof hereinafterset forth.

In order to make the invention more clearly understood, I have shown inthe accompanying drawings means for carrying the same into practicaleffect without limiting my improvements in their useful applications tothe particular constructions which for the sake of illustration I havedelineated. i l

In said drawings, Figure 1 is an elevation of a conveyer-belt supportembodying my invention. Fig. 2 is a side View of the same. Fig. 3 is aplan View. Fig. 4 is an elevation, and Fig. 5 a side View of a slightlydifferent construction of the support also embodying the invention.

Referring to the drawings, A indicates a base, suchas a metalliccasting; B, two inclined supports adapted to sustain the outer parts ofa conveying-belt C; D, the carriers for said inclined supports, and E anintermediate support for the middle part of the belt. Said inclined andintermediate supports are preferably idler pulleys or rollers, as shown;but it will be understood that all the features of my invention are notlimited to making said suppports of a revoluble character. Theintermediate support or roller E is ordinarily horizontal and is mountedon a shaft or end journals l, held in bearings 2. The latter are carriedby brackets 3 on the base A. The

- carriers D are so mounted on the base as to be hinge or fulcrum, suchas a longitudinal pivotpin 4, passing through bearings 5 on the base andbearings 6 on the carriers. On these pivots the carriers are adjustableby suitable devices capable of ready operation and of securely holdingthe carriers D and pulleys B in their .adjusted position, such asinwardly and outwardly movable slides 7 operating in directionstransverse to the belt and interposed between the carriers and the baseand supporting the carriers D from beneath by camlike bearings 8. Thetransverse movement of the slides may be effected by differentinstrumentalities, of which I have illustrated two. In Figs. 1 to 3 thebase is provided with a toothed rack 9, having a central guideway 10,and the slide is formed with corresponding teeth 11 and with a downwardprojection 12, adapted to fit said guideway. The adjustment of this formof slide is by hand, and it will be held in place when adjusted by itsweight and that of the superincumbent parts. In Figs. 4 and 5 the slides7' are adapted to be moved transversely by screws 13, bearing againsttheir outer ends and adjustable in threaded bearings 14 on the base A.Lock-nuts 15 serve to secure the screws in adjusted'position. I providefurther for forcing and holding down the carriers D, which isaccomplished by bolts'l, having their heads engaging beneath the base ora portion' thereof at 17, extending up through slots 18 in the slidesand passing through openings 19 in the carriers. Above said openingsnuts 20 on said bolts serve to force or hold down the carriers,combining with the rack-teeth or screws 13 to firmly clamp the slides.

What I claim is- 1. In a conveyer, a belt-support consisting of thecombination of two inclined pulleys, a movable carrier for each of saidpulleys operable up and down in planes transverse to the belt, anintermediate support for the belt independent of said pulleys, and meansfor operating said carriers to adjust said inclined pulleys relative tosaid intermediate support.

2. In a conveyer, a belt-support consisting of the combination of twoinclined pulleys, a carrier for each of said pulleys mounted on a hingeor fulcrum, the axis of which is longitudinal of thebelt, anintermediate support for the belt independent of said pulleys, and meansfor adjusting the said carriers around IOS their longitudinal axes tochange the positions of said pulleys relative to said intermediatesupport.

3. In a conveyer, a belt-support consisting of the combination of twoinclined pulleys, a carrier for each of said pulleys mounted on alongitudinal hinge or fulcrum and having' inner and outer bearings forthe inner and outer ends of the pulley shafts or journals` anintermediate support for the belt, and means for adjusting the saidcarriers around their longitudinal hinges.

4. In a conveyer, a belt-support consisting of the combination of twoinclined pulleys, a carrier for each of said pulleys, adjustable up anddown, and transversely-movable slides engaging said carriers foradjusting the latter.

or fulcrum on said base, and inwardly and outwardly movable slidesinterposed between said carriers and the base.

7. In a conveyer, a belt-support consisting of the combination of twoinclined pulleys, a base, a carrier for each of said pulleys, movablysupported on a hinge or fulcrum on said base, inwardly and outwardlymovable slides interposed between said carriers and the base, andconnections between the base and said carriers for holding the latterdownward.

8. In a mechanism of the class described, the combination with asuitable frame and a conVeyer-belt arranged thereon, of a plurality ot'pulleys designed to support the central portion of said belt, pulleysarranged at the ends of said central pulleys designed to support theedges of said belt, means for adjusting said end pulleys to diagonalplanes, and means for locking the same in such positions, substantiallyas set forth.

In testimony whereof I alix my signature in presence of two witnesses.
